Leviticus 25:42-46

⁴²Israelites are not to be sold as slaves because they belong to me as my slaves—I led them out of Egypt.

⁴³Don't treat them with brutality. Have respect for your God.

⁴⁴Buy your male and female slaves from the surrounding nations.

⁴⁵You can also buy them from foreigners who have come to live among you, or from their descendants born in your land. You can treat them as your property.

⁴⁶You can pass them on to your children to inherit as property after you die. You can make them slaves for life, but you must not brutally treat any of your own people, the Israelites, as a slave.
